A rigger brush has much longer hair than other types of brush and is used for painting straight lines in oil, acrylic or watercolour.Called a rigger because it was commonly used to paint the rigging on maritime paintings, the long hair absorbs any hand-shake limiting the wobble in the mark that is made and allows the artist to have fingers of the brush-holding hand resting on the surface to guide and control the line. The line should be created with one slow and steady movement of the arm.
